> Commenting to Bill’s suggestion, as I loaded this up I did look for and find those four values are defaulted, but they don’t appear to line up with the values listed in your original error for Ti (in) and To (out) for the two sides of the HX.  You might additionally try manually setting these inputs to match mine regardless of how they default in your instance:

I'm getting the following error in my file, and right now I am auto-sizing everything just to test it to get the file to run.  I cannot locate/find where the Qhx Design, SupFlow, SupTi, SupTo key words are linked too.  The heat-Exchanger: HRC-T1 is the name of my LtLHP Chiller that I input on the loops.
